## Overview

CitecScheduling is an Android scheduling app with a PHP/MySQL backend. Its visible product areas cover student and faculty access, booking and appointment workflows, schedules, availability, faculty schedule transfers, and profile functions. The sampled backend confirms registration and login APIs using a shared database connection; the Android implementation and scheduling API behavior were not excerpted, so those connections are shown only as unverified dashed links. The repository provides no README description.
